⁉️ How Not to Parse Numbers in JavaScript
Why use a proper locale-aware API to parse numbers when you can hand-roll a maze of string splits, separator swaps, and implicit type coercions that silently break on edge cases?

✌️ Four Heavyweights Drop Updates
Four stalwarts of the JavaScript ecosystem all shipped notable releases this week, and odds are you're using at least one of them:
• Gatsby v5.16 proves Gatsby, once considered neck-and-neck with Next.js in the React world, is not 'dead'. The headline feature is React 19 support.
• Babel 7 just shipped its final release. "After years in the making, Babel 8 is finally ready," in release candidate form, at least.
• Rspress 2.0 is a major release for the high-performance Rust-powered, but JavaScript-facing, static site generator.
• Lodash 4.17.23 sounds minor, but it's a 'security reset' for the still heavily used utility library and is designed to provide a base for a longer future.
